“…Side reactions that do still occur can be easily detected. One example of the GCR being used for analyzing solvent effects is the investigation of the dissociation of endo-dicyclopentadiene to cyclopentadiene [127]. It was found that the reaction rate increases with increasing liquid-phase polarity which, however, favors side reactions.…”

Chromatographic reactors integrate chemical reaction and chromatographic separation in one apparatus. This offers potential for process intensification, especially in the case of equilibrium reactions. Different types of discontinuous and continuous processes as well as modeling of chromatographic reactors are described. Synthesis and design of this processes is very much influenced and often restricted by the type of reaction and the operating window which is set by the individual operating conditions for chemical reaction, mass separation, and equipment design. Integrated chromatographic reactors should be considered if chromatography is the favored separation process for a conventional sequential process design. Preparative chromatographic reactors are known for liquid‐ and gas‐phase processes. Laboratory‐scale applications are described. Analytical chromatographic reactors are used to determine reaction rate constants and kinetics, and to screen chromatographic systems and operating conditions for preparative applications. 1.

Durch die Integration einer chemischen oder biochemischen Reaktion und einer chromatographischen Trennung in einem gemeinsamen Apparat ist es möglich, die Gleichgewichtslimitierung der Reaktion zu überwinden und die Trenneffektivität zu erhöhen. Verschiedene prozesstechnische Varianten des chromatographischen Reaktors werden vorgestellt. Aufgrund der komplexen Zusammenhänge sind Modellierung und Simulation wichtige Werkzeuge bei der Entwicklung und Gestaltung der Prozesse. Eine Übersicht über die zur Verfügung stehenden Modellansätze wird gegeben. Ein Vergleich der verschiedenen chromatographischen Simulated Moving Bed (SMB)‐Reaktoren erfolgt am Beispiel der Glucose‐Isomerisierung. In Abhängigkeit von der jeweiligen Reinheitsanforderung an den gewonnenen Fructose‐Sirup bieten unterschiedliche Integrationsgrade von Reaktion und Trennung Vorteile.
